  • Abstract
    This paper presents a comparative study of different frequency sequences which are used for Very Long Baseline Interferometry (VLBI) Bandwidth Synthesis (BWS) in recent astrometric and geodetic VLBI campaigns. The Peak Sidelobe (PS) level of Delay Resolution Function (DRF), Normalized Effective Bandwidth (NEB) and Frequency Ratio (FR) are defined as the metrics for comparison. Considering the case of loss of a channel in the sequences, its effect on the performance of the sequences are also evaluated.
